Thread: "No Skip" Category Rules

Started by: charlocharliecharlocharlie

ISOs (disc images) are banned. CTGP requires a disc to work anyway, so there isn't a concern for that.

If IOS were banned, the Wii wouldn't even run 🙂

Would IGT on that still be accepted? Also, do we have to calculate our own igt?

Recording a screen a with a camera is fine, as long as the in-game time is readable.

All runs with videos will require the runner to calculate the IGT. I made this tool a while back to make it easier.

Thread: The switch to in-game time

Started by: charlocharliecharlocharlie




Over 3 years ago, switching the leaderboard to in-game time (IGT) was first brought up.
Many of the initial objections to it were that it would be too difficult to migrate existing runs over to IGT.

In October 2017, I started calculating IGT out of curiosity. To my surprise, I found inconsistencies in load times in a few runs, and after calculating IGT for all the 'Cups' runs, I made this post.

In retrospect of the 2018 post, there are a few things I regret that I'll note here quickly:

- I feel bad about removing Insane's runs from the leaderboard. If we legalize ISO loaders, I'd love to see them back.
- Using audio spectrograms to detect Dolphin turned out to be a fluke of where the menu music was when you pressed 'OK'. There still may be something of value in analyzing the audio, but it's not as clear cut as it was in the image.

In April 2018, I started the mass conversion of all old runs to IGT, in which I requested help from fellow runners.

Also in April 2018, the category extensions leaderboard was created, which was a crucial testing grounds for the IGT-based leaderboard. This helped immensely in forming a ruleset that prevented abuse of the IGT timing method.

In July 2018, I created [mkwii-igt-calc](, a purpose-built web app that makes it easier to add up in-game times.

And 2 years later, we've finally finished converting all old and new incoming runs to IGT.


Here's some interesting (not entirely accurate) stats of the IGT conversion process:

- 1243 runs converted
- Cups: 690
- Nitro/Retro: 255
- 32 Tracks: 298
- 16376 total tracks converted


Huge shoutouts to the folks that helped convert runs:

You can preview what the leaderboard will look like by viewing a leaderboard and clicking the "In-game time" header.
Runs with an IGT will appear first, followed by any runs with RTA-only (usually proofless runs).
This makes IGT serve as a sort of "Verified" variable that you might see on other games.
If you want to compare an RTA-only run to runs with IGT, you can still sort by "Real time".



The switch will come with some rule updates, most of which come from the category extensions page. Some have already been put in place.

- A submission with video requires IGT. IGT requires video proof.
- Course order restriction and idle time limit between races
- Intentionally pausing the game mid-race is not allowed.
- USB GC Mode in CTGP is allowed again


Runs with videos but no IGT

Unfortunately, there are many videos from expired Twitch past broadcasts, or terminated YouTube channels that could not be converted to IGT. If you are one of those runners and still have the video, please re-upload and edit your run with the new video and IGT.

Other runs were so poor quality that IGT could not be seen from the video, or a part of the run was cut out. Going forward make sure that IGT can be calculated from your video.


Future proposals

Most major changes to the rules and leaderboard were put off until after the IGT switch. Once it happens, here are some topics of concern. I'll likely spin up a topic for each in the future and run a vote.

Leaderboard proposal

@MangoManMangoMan proposed setting video-less runs' IGT to the same as their RTA time, effectively giving them an IGT penalty, but still appearing grouped with the "Verified" IGT runs.

ISO loader legality

Many old runs were performed on USB/SD Card loaders, or just had fast load times that indicated the use of a loader. Legalizing ISO loaders after the IGT switch introduces more accessibility to the game, reinstates old runs, at the risk of more cheating.

Emulator legality

Similar to the ISO loader question, but with the added risk of TAS playback and emulator accuracy.


What's next

There seems to be strong support for the switch, but I'll leave this post up for about a week to let people show any objections or ask questions. If all goes well, I'll flip the switch.

In the mean time, newly submitted runs won't require IGT, but it is always appreciated.

Thread: Doing runs on CTGP

Started by: charlocharliecharlocharlie

Updated the main post to allow USB GC mode, since recent reports indicate CTGP has higher load times than vanilla, and the IGT switch will nullify the small advantage it gave.

Thread: Real Time versus In-game Time?

Started by: wastedu6wastedu6

The leaderboard is in the process of migrating to in-game time. I've had to go back and manually calculate in-game time every video recorded run on the leaderboard. There's a few dozen 32 track run remaining until I can switch it over globally. In the mean time, you can sort by in-game time by clicking the header on the leaderboard. IGT is the most accurate measure of skill and performance in the run.

I kind of want to avoid having a category for each vehicle. What do you all think about an offroading category? So maybe any vehicle with >50 OR stat https:/​/​www.​sportdoggy.​com/​mariokart/​wii.​cfm

Not all the runs are retimed as IGT yet. There's a few dozen 32-track runs remaning.
